battery jump start

A battery jump start is a method used to start a vehicle with a dead or weak battery. It involves connecting the car's battery to a working, charged battery in another vehicle using jumper cables. This transfer supplies the necessary electrical power to start the engine. Once the vehicle starts, the dead battery can be recharged through the car’s alternator. This process is quick, safe, and effective, avoiding the need to replace or manually recharge the battery immediately. Proper connection and safety precautions are essential to prevent electrical damage or injury during the jump start.
